SEEIFICATION forming part of Letters Patent No. 668,100. dated Feblualy12, 1901 Application tiled November 12, 1900. Serial No. 36,253. (Nomodela Be it known that I, CHARLES HILBERT, a citizen ofthe UnitedStates, residing at Cincinnati, in the county of I'Iamilton and State ofOhio, have invented certain new and useful Improvements in DrivingMechanism for Ice-Cream Freezers, of which the following is aspecication.

The object of my invention is to provide a power device for driving theflasher-shaft and can of an ice-cream freezer in opposite directions,with the devices so arranged that the driving-shalj'ts maybe elevated,leaving the can and freezer portion free for removal with ont disturbingthe relative arrangements of the driving devices.

The features of my invention are more fully setforth in the descriptionof the accompanying drawings, forming a part of this specification, inwhich- Figure l is a central vertical section, partly in elevation, ofmy improvement in position for use. Fig. 2 is a central vert-icalsection of parts of Fig. l, showing the shafts in their elevatedposition. Ilig. is an enlarged vertical section of the driving-shafts,their gears, and the elevating mechanism. Fig. et is an enlarged sectionon line a' at', Fig. l. l

A represents the supporting-base, upon which the freezer-tub B issupported. C represents a standard erected on said base.

d represents a means projected from the standard for engaging andholding the tub.

o represents a stud projected from the standard, upon which is asleeve-shaft c. The said sleeve-shaft supports a fly-wheel d, fast andloose pulleys e e', and a spur-gear f, the flywheel, fast pulley, andspur-gear being' fixed to turn with said sleeve-shaft. D represents ashaft journaled in the standard above the said sleeve-shaft andsubstantially parallel therewith, having iixcd to its outerend aspurgear g, meshing with the s1;iur-gearfon sleeveshaftc. On theopposite end of shaft D is a bevel-gear h. The upper end of the saidstan dard is curved over the supporting-base and terminates insubstantially if-shaped joui'- nal-arnis the upper limb 7c of whichforms a journal-bearing for the bevel-gear t' and the lower limb Zforming a journal-bearing for the bevel-gearj, said gears being in meshwith the bevel-gear @whereby they are revolved in opposite directions.The bevel-gearj is feathered and splined to a sleeve-shaft fm, revolvingin the journal-bearing Z. The lower end of sleeve-shaft m is providedwith a socket/1L.

E represents the ordinary freezer-can jou rnaled in the tub B andprovided with a topE.

o represents a boss or stem projected from the can-top, which lfits thesocket n of the sleeve-shaft on. NVithin this sleeve-shaft on is ashaftp, feathered and splined to the bevelgear z', the lower end of thisshaft being provided with a socket q, which fits the boss fr' of theflasher-shaft s, projected through the boss oi' the can-tcp.

The sleeve-shaft m has an internal offset t, and the shaft p has ashoulder u bearing against the saine, so that when the shaft p is raisedit raises with it the sleeve-shaft fm.

In order to lift the two shafts m p, respectively, from the can-top, Iprovide the following instrumentalities; F represents a sleeve seated onthe upper limb 7a of the standard and around the upper end of the shaftp. It is provided With a worm groove or slot G. H represents a stud onthe shaft p, projected into said worm-groove. I represents a hand-wheelattached to the top of said sleeve F. It will be observed that thegroove is inclined in the direction reverse to the direction o'l'revolution of the shaft p, so that the stud on said shaft will bearagainst the lower extremity of the groove when the shaft is revolved andcarries said wheel with it in its revolution. When it is desired to liftthe driving-shafts, however, the handwheel is turned in the samedirection and the stud on sh'aft p will travel up the incline and intothe straight end of the incline II, which forms a rest, thus lifting theshafts p fm, which slide respectively through their bevelgears t' j andfree their sockets, respectively7 from the dasher-shaft and can-top. Thecan is thus permitted to be taken from the tub without in any wisedisturbing the arrangement of the driving parts. It will be observedthat the upward movement of the said shafts is represented by theopposing faces of the bevel-gears t' j; but this is suiiicient toprovide space for the removal of the can or tub.

Having described my invention, I claiml. The combination in a powerdevice for ice-cream freezers of a standard, right and IOO left handbevel-gearsjournaled one abovethe other o'n the standard, a sieeve-shaftsplined to the lower gear and adapted to be socketed to the can-top, aninternal shaft splined to the upper gear and adapted to be socketed tothe flasher-shaft, the said shaft being offset into the sleeve-shaft,whereby they will both be raised with the internal shaft, a sleevemounted o n the internal shaft above the journaled support for the uppergear, a worm-groove formed in the said sleeve, a projection on theinternal shaft vengaging into this groove, and a hand-wheel on the saidworm-sleeve adapted to raise the said shaft, substantially as specified.

2. The combination in 'a power devicefor ice-.cream freezers of astandard, right and left handl bevel-gears journaled one above the otheron the standard, asleeve-shaft splined to the lower gearz and adapted tobe socketed to the can-top, an internal shaft splined to the upper'kgeary and adapted to be socketed to the dasher-shaft, the saidshaftbeing offset into thesleeve-shaft, whereby they Will both be raised withthe internal shaft, a sleeve mounted on the internal shafty above thevjournaled support for the upper gear, a worin-groove formed in the saidsleeve, in a direction of inclination the reverse to the esame directiono f rotation of the said shaft, a projection of the internalI shaftengaging into this groove, and a hand-wheel on the said worm-sleeveadapted to raise the said shaft, substantially as specified.

3. I n combination with a power device for ice-cream freezers, astandard, right and left hand bevel-gears journaled thereon, asleeveshaft and anl internal shaft splined respectively to the saidgears and adapted to be socketed respectively to the can-top and thedashershaft, said shafts being adapted to be raised in unison, theinternal'shaft projected upwardlythrough the sleeve-shaft and having aprojection thereon, a worm-sleeve journaled around the upper end of saidinternal shaft having a groove inclined in a direction reverse to therotation ofthe yshaft which receives thel said-S projection in theshaft, the said groove terminatingv in a straight horizontal planeforming a; rest forA the internal shaftwhen itis raised, and aWorm-wheelon the sleeve, substantially as speciiied.

In testimony whereof I have hereunto set my hand.
